" To all whom it may concern:

7 thereof. I

1 ment of the ground-engaging or tread mem- Beit known that I, Wrens- PETERSON, citizen of-the United'States, residing at St. Anthony,- in the county of Fremont and State of Idaho, have invented new and useful Improvementsin Tractor-Wheels, of which the following is a specification.

The object ofmy present sole invention is the provision of atractor wheel' possessed of considerabletractive capacity and adapted to absorb shocksand strains due to bad roads, and to prevent the transmission of'the same to the vehicle'equi-pped with the'wheel. 7 I To the attainment ofthe' foregoing the invention consists in the peculiar and advantageous tractor wheel hereinafter described and definitely claimedr In :the accompanying drawings, hereby made a-parthereof: r Figure 1. is a side elevation of the tractor wheehconstituting the best practical em bodiment of my invention ofwhich Iv am cognizant vith a portion of the rim flange broken awayto show the relative arrangebers of the wheel. I V a F 1g. 2 is a longitudlnal vertical section taken through pluralityof almed tread members to show the relatlve arrangement Fig. 3 is a view, in plan, of the perimeter of the wheel and showing the staggered re lation of the tread members in the several parallel series. 7

Fig. 4 is an end elevation of one of the tread members.

Fig 5 is a transverse section taken in the plane indicated by the line 55 of Fi 3. V Fig. 6 is a detail plan view showing a portion of the rim of the wheel, with the tread members removed.

Fig. 7 is a perspeotiveof one of the tread members, Similar numerals of reference designate corresponding parts in all of the views of the drawings. v The rim 1 of my novel wheel is provided with side peripheral flanges 2 and intermediate peripheral flanges 3.

In the spaces between the said flanges are arranged circular sets of tread members 4,

the tread members in the several circular sets or series being arranged in staggered relation, as appears in Fig. 3, with a view to enabling the tread members of the several series to engage the. ground or 'roadway incidental to rotation of the wheel in succession, and in that way contribute to the tractive capacity of the wheel. The several tread members 4 are identical in construction, and therefore a detailed description of one tread member 4 will suflice to impart a definite understanding of all. In other words, each of the tread members 4 comprises a body wall 5, recessed at 6 to clear the head of an adjacent connecting bolt 7 side walls 8 disposed at right angles.

to the body wall5, and recessed at '9 when necessary to clear an adjacent-bolt 7, and end walls 10 of V-shape in cross-section connected to and extending inwardly from the ends of theside walls 8. Manifestly the edges of the side walls 8 and end walls,

10 are adapted to sink into the ground or roadway, and it Wlll be noticed-in this connection that the side walls are recessed at 11, so that the end portions of said side;

walls will be embedded in the ground or in a roadway to a greater extent than the intermediate portions of the side wall. This provision is advantageous because it lessens the liability of the members 4 becoming clogged with dirt, and also because it facili tates the removal of caked dirt from the members 4 when the sameis necessary. Each member 4 is connected to the peripheral flanges between which it is arranged by means of one of the bolts 7 the said bolt 7 being arranged in slots 12 in the side walls 8 of the member, as shown, so as to permit of bodily movement of the member 4 between two of the peripheral flanges and toward and from the center of the wheel. It will further be observed that each of the members 4 is provided at its forward end with reference to the direction indicated by arrow in which the wheel is intended to be driven,.with a cross-rod 13, and is provided at its rear end with a rearward extension or tongue 14 that is disposed at the Patented se e mfloao.

inner side of the cross-rod 13 of the next ward end of the next forward or preceding wheel. In this connection it'will be understood that thectongne 14; on each tread brlngs about the results stated by thrusting upwardly against the forwardend of thebody wall of the next preceding tread member.

Interposedbetween and retained between,

the rim-1 of the wheel andcentralportion of each :of the tread members 4 is'a coiled spring 15. By virtue of this provision the tread members 4; are cushioned, with they result that the wheel is adaptedto absorb shocks and; j arsand prevent the transmiss i "sion ofstrain to the vehicle equipped with g the wheel. 7

The staggered arrangement of the treadmembers et ofthe several series 1s advantar 'geous, because it assures 0116 :Ofthe tread Inembersbeing in full engagement with, the ground at all times, with the result thatthe tractive, capacity of the wheel is inc1-'eased:--

It will-be apparent from the foregoing that-'my, novel wheel is'simple and ineX-I pensive in construction, and yet is designed to occupy the field betweenthat of the small tractorwheeh and that of the track laying tractor. ,It will also be apparent that in the use ofmy novel wheeh a considerable number of the tread members will at all-times beinengagement withthe ground or road way, with the result thatample traction is affordedfor, general purposes. i

' I-Iaving described" mylnventlon, what claim and. desire; to secure. by Letters-Patcut, is

a rimhaving spaced and parallel peripheral bridging said spaces,

1. In a tractor wheehth'e combination of flan es bolts carried said flanges and the ground is enabled to raise the rear end of the next, forward-tread member in its seg ries, and a spring interposed between the central portion of each tread member. and. the rim, wherebythe wheel is cushioned. 2. .Ina tractor wheel, the combination of and tread members receiving and movable bodilyion the bolts 7 having forwardly extending tongues, whereby each tread member asiits forward end is forced upwardly by engagement with 7 a rim having spaced and parallel peripheral flanges, bolts carried by said flanges and bridgingv said; spaces, and tread members receiving and movable bodilv on the bolts and having, forwardly extending tongues, whereby each tread member. as its forward end is forced upwardly by, engagement with the ground is enabled to raisethe rear end of the next forward tread member inxits series, and, a springinterposed between the. central portion of each tread member and the rim, whereby the wheel is cushioned; thetread; members inthe several series being arranged in staggered-relation,

3. In a tractor wheel, the combination of a having, peripheral spaced flanges, bolts bridging the space between the flanges, and a circular series of tread members .movable-i bodily on the bolts between theflanges and each tread member-having a forwardly extending. tongue arranged to raise the rear end ofn-thenext forward or. preceding tread member, the, saidtread members being backed by. springs interposed between the same and the rim. 7
